IMPROVEMENT IN TOOL FOR FITTING BANDS 0N HUBS.

TO .ALL WHOM IT MAY CONCERN:

I Be it known that we, CHARLES E. S'ronaof Amesbury, and ALFRED HERBERT,of Salisbury, in the county of Essex,` and State of Massachusetts, haveinvented a new and useful Improvement in Hub-Band Fitters; and we dohereby declare that the following is a full, clear, and exactdescription vthereof, which Willenable others skilled in thc art' tomake and use the same, reference being had to the accompanying drawing,forming part of this specification, in whichl The drawing represents a.side view of our invention, shown as applied in practice. Similar`letters ot' reference indicate like parts. p Our invention is animprovement npon a tool for fitting hub-bands, which has been in use forsome years. Said tool consists of a single handle, recessed, andprovided with two cutters arranged at right angles to each other. It wasfoundv diiicult to execute work satisfactorily with this tool, however,for the reason that it was not provided with a/clamping-devicc. Theobject of our invention is to remedy this defect by supplying aclamping-lever, by means of which the fitting of hub-bands is renderedeasy.

Heretoore, hub-bands were fitted to the' hub by chipping oit` a portionof the wood with a hammer and chisel, until the end of the hub was ofthe right perimeter to receive the band. VThis method was laborious,requiring both skill and time to accomplish the proper fitting of theband.

By our invention, the operation of chipping ofi the hub with'a chisel isdispensed with, and a continuousv shaving is pared from the hubbye-imply turning the wheel on its axle, and holdin-g the tool in properpositionupon the hub, as will hereinafter be duly set forth.

The invention consists of two handles, -A and B, pivoted together 'oymeans of the arm C, forming part of the handle A, together with otherdevices perfecting the whole, and which will now be described.

The handle B is provided with a set-screw, a, which is screwed into anyone oi' the several holes b b b, formed in theV arm C, as shown, and, bymeans of `this set-screw and the said' holes, the handles are pivotedtogether, at suitable distances apart, to adapt the tool todifferent-sized hubs. I

The handle B is formed with an angle or concave, as shown at c c c, forthe purpose of conforming suiciently to4 hubs of different sizes, and tobear upon the surfaces ofthe hubs at two points, and thereby be enabledto be held firmly in a iii/red position against the hub during theVoperation'of cutting or paring the same.- p

The handle A is formed with a recess, E, for the escape ofthe paring orshaving cut from the hub by the vcutter (Z, bolted or otherwise afxed tothe said, handle, so that its cutting-edge shall project sufficientlytoencounter the hub, as indicated in thedrawing.

A marking-cutter c 'is fitted in a dove-tailed slot in the handle A, andpresents its point to the hub to mark and cut a vertical' incision intothe hub, whereby the ilnt cutter (Z is enabled to operate moreeiectively in cutting a lclean Vsent for the reception ofthe band. i i

Themarking-cutter e is clamped in position by any suitable device, asthe lateral .set-screw, shown dotted ntf.

The ilat cutter is slotted to enable it 'to be set to eut more or lessdeeply, as required, and its set-screw, g, is within the slot. l l

In the operation of fitting the band, theptool is applied, as shown inthe drawing. It is'held by the handle, and the wheel revolved upon itsaxle until a snilieient thickness of wood has been cut oii' to enablethe band to fit tightly upon the hub. .y i

We are am aware that a hub-band fitter, consisting of a single handle,recessed, and provided with two cutters arranged at right angles to eachother, has been used before, -but this we disclaim, as it forms no partof our invention. I

Having thus described our invention, we claim as new, and desiretosecure by Letters Patent- The handle B, curved at c c c, and adjustablypivoted'to the extension C `ofthe handle A, by means oi` tho set-screw afitted into either one of a series of holes, b Z1 6, formed .in said armC, substantially as and for the purpose herein shown and described.

ALFRED HERBERT.
